l 'd Application filed January 12 190,1.3 Serial No; 43,040. (No model.)

To all whom t maylconcern:

citizen of the United States, residing at Cincinnati, in the countyof Hamilton'and State' l of Ohio, have inventedrcertain new and useful Improvements in Door-Guards, of which the followingis a specification. d

My invention relates to a guard for that class of doors which `when opened out leave `an exposed trap `or opening constituting an element of danger`lsuch as-doors of cellars, freightand elevatorchutes, and numerous otherv doors involved-in this class.

My guard is adaptedY to be applied to the inside of a door andiexpanded yinto position l to cover a gap o'f-,greater o r less dimension..

The features of myinventionwill be more fully sot forth in the description of the accompanying drawings, forming a part ot this 2o specification, in whichguard in position for use. Fig. 2 is aview showing the guard in its folded position upon the inside'of a cellar-door. Fig. 3 is a-perspective View of theshield-lock. Fig. 4 is a central vertical section through the hinge. Fig. `5 is a section on lineman', Fig. 1. Fig. 6 is a section on line y y, Fig. 4. Fig. 7is a sectional View of the central link connection on line z e', Fig. 1. Fig. 8 is a frontelevation of one of the hinge-supports.

My guard consists of a series ofiextensibleY and folding link-bars which when extended form a vertical gate or barrier spanning the space exposed by the opening of the door. The two endflinksare each made of halt'- length, as will be seen by reference'to Fig; 1-

of the drawings.

A represents one of the hinged doors, to

rigid shield D, which is in turn rigidly sewhich is secured a door-plate A', provided, with lugs c c', to which is pivoted a U-shaped.

.to limit the movement of theextensible bar, vhinge B is provided with anrved slot Vc represents-a pin secured to the link aand Atraveling in said slot ,7",thust limiting the ls s movement of the, links and distributing the strain to the two opposing doors. This form v of hinge embracing the links a considerable distance each'side of the center forms a guide as well as a support for the extended' links.

In the preferred form `otconstructionthe hinge B is notched, so as to Apass over a lug v Z, projecting from the Ydoor-plateA.

* Z' represents'a lug onjthe link a, which assists in supporting the weight of the collapsi-v -ble door-guard and removing the strain partiallyfroln the hingelB and forming ya support for the doonitself. fThe shield D on the door E supports the free or extreme end of the guard, thereby making a rigid support for y the links when extended.

H represents a locking-catch-hinged to'the i shield D, so as to lock the extensible guard or gate and prevent its accidental disengagement. i i

L represents stay-chains securedto ,the cellar-door and attached to a central staple, so as to prevent undue `when open.

In order to secure the extensible gate or guard in its position on ythedoor A, I provide strain upon the guard a pivoted catch M, having onits periphery d stops fm, which are adapted to engage witha pin n to hold the catch in its respectivepositions. y

In order that the gateor guard when extend',- ed shall be relieved of tendency to swing on hingeB, I provide the following instrumentalities When the links are ,fully extended, the lug Z' on the link-section a. hasv passed out of engagement with the ylug Z on the door A,

This lng `ist provided loo Y u represents a lug upon the door-plate A, and w a lug upon thehinge B. This prevents the guard when closed from swinging outward, but does not interfere with the inward swing of the guard.

In order to lock the gate` more effectively in its extended position, the guide-pin 7c is threaded into the link ct and the head thereof serrated, so that it may be easily turned to clamp the link against the side of the hinge B.

In order that the central pivot-bolts of the link system may be made firm and strong, as well as to secure their easy movement, I provide the following instrumentalities: Fig. 7 represents a cross-section taken through the center bolt or rivet r on line .e s, Fig. l, d e representing the links, r the center bolt, s a brass ring which is inclosed in an annular cavity on the inner faces of the links or bars d e, all the joints throughout the series of links being constructed in this manner and made of brass to prevent rusting or sticking of the parts. The links are shown of concavo-convex form,as mosteconomical; but the joint-sections of the link are flattened upon each side to make better bearings and to allow the bolt-heads to rest flush upon the links, as shown in Fig. 7.

Having described my invention, I claim- 1.- In a safety gate or guard for hatehwaydoors, a gate or guard attached to a door at one end, and a hook having parallel sides adapted to engage with the other end of said guard, substantially as set forth.

2. In a safety gate or guard for hatchwaydoors, a brace hinged thereto, and a folding gate or guard pivoted at one end to said brace nearits center, said gate being carried by the brace, 'substantially as set forth.

3. In a door-guard, a hinge attached to the door, a lazy-tongs gate pivoted to said hinge by the end pivot of its central line, and means for engaging the free end of the gate when extended, substantially as specified.

4. In a door-guard, a hinge attached to a cellar-door, a lazy-tongs gate, the central end pivot of which is pivoted to said hinge, and

a catch fixed to said cellar-door adapted tok engage the outer end of the gate when col 'lapsed and folding inwardly against the door,

substantially as specified.

5. In a door-guard, a hinge attached to a cellar-door, a folding gate pivoted to the hinge, and means attached to the door adapted to engage the hinge and limit the lateral swing of the gate, substantially as specified.

6. In a door-guard, a hinge attached to the door a folding gate pivoted to said hinge, a lug attached to the door adapted to be engaged by the link-barwhen the gate is folded in and released when the gate is extended, whereby the hinge slides in its bearings, and devices attached to the door and hinge respectively adapted to interlock when the gate is swung to its central 'position and extended outwardly, substantially as specified.

7. A door-guard consisting of an extensible gate pivoted to a hinge which is in turn pivoted to a swinging door, and mea'ns connected to said hinge and door whereby the hinge is dropped automotically and locked against the hinge action, when the gate is extended, substantially as specified.

S. In a door-guard, a swinging door, a hinge attached thereto, a lazy-tongs gate, the central joint of the first link-sections of said gate being pivoted to said hinge, means on the said door for engaging and retaining the free end of the gate when contracted and folded inward against the side of said door, and means on the opposite door for engaging and retaining the free end of the gate when extended aeross the aperture to be guarded, substantially as specified.

9. In a door-guard, a plate, a guard-hinge attached thereto, composed of oppositelyprojected limbs, a folding gate pivoted between the limbs of said hinge, and interlocking devices on said plate and hinge adapted to engage when the gate is swung to a predetermined position, substantially as specified.

In testimony whereof I have hereunto set my hand.
